[OE-core] Kernel fails to build in do_populate_sysroot after OE-core upgrade

[Mike Looijmans]

I expect this is related somehow to the recent change in the kernel to use 
hardlinks, but I have no idea what's going wrong here.

This is the recipe for the kernel, which has run fine so far.

This is the output log:
